Copernicus was likely not just a stray but a feral kitten when Suw and Kevin adopted him. That caused conflict between himself and Suw's two older cats, the late Mewton, and Grabbity. The slow introductions, sharing scents and playing with them together that many recommend did not work; and the delicate peace never lasted long.

Suw and Kevin persevered, and now Copernicus and Grabbity are best of friends. Suw talks to Ewan about adopting Copernicus, dealing with his challenging behaviour over many years, and how he found peace within the house and with Grabbity.
